OAR-LOCK.

SPECIFICATION forming part of Letters Patent No. 680,289, dated August13, 1901.

Application filed December 15, 1900. Serial 1111.401048. (No model.)

To all whom it may oon/cern:

Be it known that I, WILLIAM L. STTERLIN, a citizen of the UnitedStates,residing at Trenton, in the county of Mercer and State of NewJersey, have invented new and useful Improvement-s in Oar-Locks, ofwhich the following is a specification.

This invention relates to new and useful improvementsin oar-locks; andits primary object is to provide a device of simple and durableconstruction which may be readily secured to gunwales of a boat andwhich is provided with means whereby the same is prevented from beingwithdrawn therefrom except as desired.

An other object is to provide means of novel construction, whereby theoars will be held securely within the oar-lock.

With these and other objects in view the invention consists in providingastem which is provided at its upper end with a yoke of ordinaryconstruction. To each end of this yoke is pivoted a dog having aninwardly-extending portion and a weighted outer portion, said outerportion being adapted to hold the inner extensions normally in asubstantially horizontal position. Dogs are also pivoted to the stem atthe lower end thereof and are normally held in a horizontal position,but may be, if desired, swung vertically into recesses providedtherefor,thereby perlnittin g the oarlock to be readily removed from thegunwale in which it is mounted.

The invention also consists in the further novel construction andcombination of parts hereinafter more fully described and claimed, andillustrated in the accompanying drawings, showing the preferred form ofmy invention, and in which- Figure 1 is a side elevation of the devicein position upon the gunwale of aboat. Fig. 2 is a central verticalsection through the de; vice, showing the stem in elevation. Fig. 3 isan end view of a modified form of oar-lock; and Figs. 4: and 5 aredetail views of a portion of the stem of a modified form of oar-look andof a receiving-plate therefor,respectively.

Referring to the figures by numerals of reference, l is a stem providedat its upper end with a yoke 2, having a shoulder 3, which is adapted tobear upon the gunwale of the boat. To each end of this yoke 2 is pivotedvent the upward movement of an oar after the same has once been placedwithin the yoke. These dogs 4 are, as shown in Fig. 2, preferablypivoted within recesses formed at the ends of the yoke. The stern 1 isrecessed on opposite sides at points adjacent to its lower end, as at 7,and within each recess is pivoted a dog S. rlhe lower walls of therecesses are adapted to support these dogs non mally in horizontalposition and the dogs are so mounted as to extend in opposite directionsfrom the shank. The recesses "7 are large enough to permit the dogs toswing thereinto when raised.

It Vwill be readily seen that when it is desired to secure the oar-lockwithin a gunwale the stem 1 is inserted into the proper aperture,forcing the dogs 8 up into their recesses 7. As soon as these recessespass below the opening within the gunwale the dogs 8 will fall outwardby force of gravity and will prevent the withdrawal of the stem untilthey have been swung upward into their respective recesses.

When it is desired to place an oar within the yoke 2, the same is placedupon the extensions 6 of the dogs 4, forcing the same downward until theends thereof are passed by the oar. The weighted ends 5 of the dogs willthen swing the extensions 6 upward to their normal positions. The upwardmovement of the oar: will be prevented until said extensions are presseddownward.

While I prefer the construction hereinbefore described, I do not limitmyself thereto, for, if desired, the dogs 4 may be pivoted Within slotsformed within the ends of the yoke 2, and the dogs 8 may be -similarlymounted Within a slot 9 in the stem 1. This construction I haveillustrated in Fig. 3.

In the foregoing description I have embodied the preferred form of myinvention; but I do not limit myself thereto, as I am aware thatmodifications may be made therein without departing from the spirit orsacriicing the advantages thereof, and I therefore ICO reserve the rightto make all such changes as may fairly fall within the scope of thefollowing claims. Among these modifications is the one which I haveillustrated in Figs. 4 and 5. With this construction of oar-lock thepivoted dogs 8 in the stein are dispensed with and lugs l0 employed inlieu thereol". These lugs are adapted to be in alinement with the armsof the yoke, and plate 11 is adapted to be secured to the gunwale and toreceive the stem. Recesses l2 are suitably located within the sides ofthis plate, so as to permit the lugs lO` portion and an outer 1luwardly-extendng portion vtothe dog; and a Weighted outer end to thedog adapted to hold the inner extension normally in a horizontalposition.

3. In an oar-lock, the combination with a yoke; of astein thereto havingrecesses therein; and a dog pivoted within each recess, said dogs beingsupported normally in a horizontal position by the end walls of therecesses.

4. In an oar-lock, the combination with a yoke; 'of dogs pivoted to theends thereof; inwardly-extending portions to the dogs; outer Weightedportions thereto; a stem; dogs pivoted Within recesses'of the stem andadapted Ato normally extend laterally from said stem in oppositedirections and to be retracted into the recesses.

In testimony whereof I affix my signature in presence of two witnesses.
